Most distant blazar is a high-energy astrophysics puzzle

(Phys.org) —Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of the blazar known as PKS 1424+240 show that it is the most distant known source of very high-energy ...

'Spooky action at a distance' aboard the ISS

(Phys.org) —Albert Einstein famously described quantum entanglement as "spooky action at distance"; however, up until now experiments that examine this peculiar aspect of physics have been limited to relatively small distances ...

Designing a better satellite

(Phys.org) —If you have ever plugged your digital camera into your desktop to download photos, then you have used what is known in computing circles as a "plug and play" interface. Basically, plug and play refers to any ...

Measuring Mars: The MAVEN magnetometer (w/ video)

When the Mars Atmosphere and Volatile Evolution (MAVEN) mission begins its journey to the Red Planet in 2013, it will carry a sensitive magnetic-field instrument built and tested by a team at NASA's Goddard Space Flight Center ...

Space race under way to create quantum satellite

In this month's special edition of Physics World, focusing on quantum physics, Thomas Jennewein and Brendon Higgins from the Institute for Quantum Computing at the University of Waterloo, Canada, describe how a quantum space ...

Third radiation belt can wrap around Earth, probes reveal

With the flip of a switch, a pair of instruments designed and built by the University of Colorado Boulder and flying onboard twin NASA space probes have forced the revision of a 50-year-old theory about the structure of the ...

MAVEN mission completes assembly, begins environmental testing

NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft is assembled and is undergoing environmental testing at Lockheed Martin Space Systems facilities, near Denver, Colo. MAVEN is the next mission to Mars and will ...

Researchers pushing boundaries of virtual reality

UT Dallas researchers are extending the borders of virtual reality, going beyond virtual spaces in which people can see and hear each other to an environment that adds the sense of touch.
